Optical rectification coefficient of a two-dimensional parabolic quantum dot: Effects of hydrogenic impurity, external fields, hydrostatic pressure and temperature

Abstract

Simultaneous effects of hydrogenic impurity, hydrostatic pressure, temperature and external electric and magnetic fields on the intersubband optical rectification coefficient of a two-dimensional parabolic quantum dot are studied. Energy eigenvalues and eigenvectors are calculated using the direct matrix diagonalization method and optical rectification coefficient is obtained via the compact density matrix approach. The results indicate that the optical rectification coefficient is affected by the hydrogenic impurity, hydrostatic pressure, temperature and external fields.
